1. Introdução
The TOPDON BT100 is a versatile 12V automotive battery tester designed to provide critical information about battery health status. It performs a comprehensive analysis of various 12V lead-acid batteries, including regular flooded, AGM flat plate, AGM spiral, GEL, and EFB types, with a test range of 100-2000 CCA. This device is suitable for a broad array of vehicles such as cars, trucks, marine vessels, motorcycles, RVs, ATVs, SUVs, boats, yachts, mowers, and golf carts. It quickly and accurately identifies battery and charging problems, offering insights into voltage charge, internal resistance, and aging status.
The BT100 also conducts cranking system tests and alternator charging tests, making it an essential tool for DIY enthusiasts, auto repair shops, and battery manufacturers. Its user-friendly interface and smart LED indicators simplify the diagnostic process, allowing for quick assessment of battery condition.
2. Informações de segurança
It is important to always turn off your vehicle's ignition when testing your battery. Always read the safety features section in the manual carefully to ensure optimum safety. Batteries can be dangerous and require respect. Follow all safety rules and the correct order of installing and removing clamps aos terminais da bateria.
- Conectando Clamps: Connect the RED POSITIVE (+) lead FIRST. Then connect the BLACK NEGATIVE (-) lead SECOND.
- Removing Clamps: Disconnect the BLACK NEGATIVE (-) lead FIRST. Then disconnect the RED POSITIVE (+) lead SECOND.
- Always use eye protection and never place your face directly over the battery.
- Ensure battery terminals are clean for accurate readings. Corroded terminals can lead to incorrect test results.
